What surgical procedure involves the removal of the distal 3/4 of the stomach?

The surgical procedure that involves the removal of the distal 3/4 of the stomach is known as subtotal gastrectomy. This procedure typically leaves a portion of the stomach intact, specifically the proximal part, and is often performed to treat conditions such as malignancy or severe peptic ulcer disease.

During subtotal gastrectomy, the surgeon removes the majority of the stomach, which can help alleviate symptoms and improve the patient's quality of life while preserving the initial portion that is responsible for some digestive function. This makes it distinct from a total gastrectomy, where all of the stomach is removed.

While partial gastrectomy can refer to a variety of stomach resections, the term "subtotal" explicitly conveys that a significant portion is taken while retaining some function, aligning with the definition provided in the context of removing the distal 3/4 specifically. Hence, subtotal gastrectomy is the most accurate term for this surgical procedure.
